Hippocrates’ Good News Survey.
The study was correlational. In its definition, a correlational study tries to determine how variables may be related, usually in a way that can be predicted. The two variables, in this case, are the meal that is taken and cancer. They form the baseline of the research. Moreover, the study was based on children who are presumed to be of the same age group. Nevertheless, the study did not focus on the environment they were subjected to, the race difference and the other types of meals they integrated into their diet.
The race of the study group, the other meals, and the environment are some of the factors that may be used to explain the difference. As such, being in a carcinogenic environment, having meals that may increase the chances of cancer and the vulnerability of a specific race to cancer may be used.
